Pissing all over myself on an old couch in the desert

I start off by wetting my jeans sitting near a road with traffic passing by behind me, then I drive out into the desert and find a couch someone dumped. By the time I get there, I am super desperate. I sit on the couch and let loose an absolute fountain of piss all over myself, in my mouth, and on my jeans and shirt before cum blasts out of my cock.
